The US Food and Drug Administration has issued warnings to companies that claim to offer therapies or cures for autism. In a statement commemorating National Autism Awareness Month, the FDA noted a handful of medications that it has previously approved for use in autism treatment, as well as therapies to help specific symptoms. But health fraud coordinator Gary Coody said that a number of companies have been told to stop making misleading claims or face legal action. Of the five treatments the FDA cites, some have legitimate medical uses — they just havent been shown to help autism.
